The latest course of pollution-free fertilization techniques and methods for cherries

Cherry is a kind of ditch with high economic value, which has a very large market in our country and is loved by many people. Now the planting area of cherries in China is relatively large, when planting cherries, we must do a good job of fertilization to provide adequate nutrition for the growth of cherries. But how should we carry out pollution-free fertilization? The following editor will give you a brief introduction, let's have a look!

1. Ditch application

Ditch application can be divided into radiation ditch method and ring ditch method. When using the radiation trench method, the trench should be dug around the 50cm at the base of the trunk, based on the principle of narrow inside and wide outside. The depth of the inner groove is about 30cm, and the depth of the outer groove is about 45 cm. Each tree dug about 5 trenches to fertilize. Then use the ring trench, dig the trench in the shadow of the crown, the width is controlled at 50cm, the depth of 45cm. No matter what the ditch is, after digging the ditch, fully mix the fertilizer and soil into the ditch, and pay attention to watering after fertilization.

2. Sashi

For spreading, it should be determined by the root distribution of the cherry trees in the garden. If the root system in the garden is widely distributed and the root capacity is strong, then the spreading method can be used for full fertilization. First of all, we should prepare the fertilizer, spread the fertilizer comprehensively and evenly into the orchard, and then turn the soil deeply to mix the fertilizer into the soil. The depth of deep turning should be controlled around 20cm, and it should not be too shallow or too deep, otherwise it will easily lead to root floating, affect root growth and reduce root disease resistance.

3. Acupoint application

First of all, it is necessary to dig a fertilizer hole with a depth of about 40 cm along the crown, add an appropriate amount of grass handle to the hole, and control the specification of the grass handle. Apply an appropriate amount of nutrient solution to the fertilizer application point. The number of fertilizer holes depends on the size of the cherry tree. Usually a tree digging holes of about 5, after digging holes to fertilize, we should pay attention to cover plastic film. Poke a small hole in the middle of the plastic film to carry out water and fertilizer work. After watering and fertilizing, we should pay attention to sealing the small hole to avoid evaporation. If it doesn't rain, 5kg will be watered for about three weeks.

4. Foliar fertilization

In the cherry growing period, we also have to do a good job of foliar topdressing of cherries. Foliar fertilization can effectively improve the absorption rate of fertilizer and distribute nutrients evenly. Cherry foliar fertilizer should choose urea, ammonium phosphate, potassium phosphate and other fertilizers. It can be sprayed properly until the growth of cherry leaves stops. However, it can not be carried out at noon in summer, where the high temperature leads to drug damage. It is usually sprayed every 2-3 weeks. Before fertilizing, the fertilizer needs to be dissolved and then sprayed.

The above is a brief introduction of pollution-free fertilization technology for cherries. The fertilization method of cherry is very important, we must pay more attention to it. So that's all for today's introduction. This article is for reference only. I hope it can help you all.
